Bad service and lying to call costumers back

I called Telkom from the month of January as I needed insurance for my phone. I dealt with numerous consultants that could not assist me. I took out insurance with them but everyone I called them they said I have no insurance. Clearly the consultants did not know where to look if I was insued or not. They send me an invoice for month's and according to my understand I don't have insurance, I was not called to be notified Of this and when I ask why was I not notified I am being told I will be called back and up until now I'm still waiting for this call. Telkom should provide staff with the necessary training as they are clearly clueless. The worst service I ever got from a company how disappointing for a worldwide company expected to deliver exceptional service.
